    OK, I changed the filter on the frame in my K5 (89 TBI) and I am wondering if that is the only fuel filter it has??? help would be appreciated.

    Solowookie,
    I have an 87 and a while ago I went over all the lines from the tank to the TBI looking for a fuel leak and the only filter on mine is the one on the frame rail passanger side.
    Hope that helps,
    Andy (Bowtied)

    That is the only one except for the pick-up screen on the tank mounted pump.

    The one on the frame is the only one on the fuel lines.
    There is also a filter on each injector. You have to remove the injector from the fuel meter body to get to it.
    In the gas tank there is a strainer on the fuel pick up that stops particles big enough to damage the pump. If it gets twisted or damaged( this can happen when siphoning gas) it can restrict fuel flow. Blowing air back thorugh the fuel line can sometimes unclog it.
    These are all the stock filters on a TBI system that I know of.

    hey guys thanks a ton for the info. I put some Lucas in so when I get through this tank of gas it should clean out the injectors if there is a problems.

    when I added Lucas in my Grand Prix in had 40,000 miles on it. it ran good, but gas milage was horrible. I gained back 3 MPG with this stuff! (awesome stuff)

    Lucas? What's this miracle stuff?

    The only Lucas I've heard of before was the Prince Of Darkness British electrical company. [​IMG]

    Lucus is awsome! They make it as a fuel additive, tranny additive...just about anything I believe and it's all good! I think they make some to go in the diff and standard trannies.

    I've got a mind like a . . . a . . . what's that thing called?

    the stuff that goes in the diff and trannies (manual) is the same stuff that goes in the engine. you just put it in with differenct percentages.
